Description of the Invention: [Technical Field] The present invention relates to a method of disposing a rewritable optical disc, which comprises the identification of a disc type and the installation of a logical structure. The invention also relates to a device for recording a rewritable optical disc and a computer software product. [Prior Art] When a disc is inserted into a drive unit, several actions must be successfully executed so that the information can be read or recorded on the disc. First, the exact disc type must be identified so that the reading device can be adapted to the reading and/or recording method for that disc type. Second, the disc needs to be installed. This step involves reading the logical file structure. If both steps are successful, the disc becomes a usable disc that can be used by the end user. If a bug is detected during the disc identification step or during installation, a known drive will report a disc damage 'and the end user cannot use the disc. However, this is not an end to the end user, as the end user may not have other discs available and may be interested in still using the disc. SUMMARY OF THE INVENTION The present invention is directed to providing a solution to the above problems, which allows a user to use a particular type of report that is damaged. The object of the present invention is achieved by the method according to the present invention for the treatment of the scorpion 剞 地 』 』 』 。 。 。 。 。. In the method according to the present invention, the steps of the private steps of each of the hoppers and the 乂L are after the installation step, which includes if the type of the disc has been identified in the slap recognition step, but For information on the structure of the logical disc, white male, ° 匕 3 error or unreadable, format the light 120484.doc 200813999. This is based on the understanding that a disc that is not installed because a particular logical disc structure cannot be read should still be formattable. Formatting allows the disc to be reused at the expense of losing all stored information, and it should be feasible, it only requires the availability of information obtained during disc recognition, and does not require any logical discs already present on the disc. Information on the structure of the film. Although the discrimination between different types of discs (for example between CD and DVD) is often done with beam parameters 'further discrimination (eg between DVD+RW, DVD_RW, and DVD_RAM) can be recorded in the lead-in area (lead-in) The information in the area is known from the information recorded in the wobble during the manufacturing period. It is advantageous to capture information that is pre-recorded in the swing because it does not require the ability to record data. In an advantageous embodiment, the method further comprises a recovery step prior to the formatting step, if the information about the logical disc structure comprises a misrecognition 'recovery step comprising recovering at least part of the storage on the optical disc prior to the formatting step User profile. Errors encountered during the installation step can be errors in the retrieval of disc management information or in the retrieval of file system information. In the latter case, it is possible to partially install the file system. It is advantageous to restore information stored in properly installed files in such κ cases. In an advantageous embodiment of one of the methods, defect management is enabled during formatting. In general, the use of defect management is optional. However, considering the fact that the previous attempts to install the disc failed, the disc is more likely to have an unavailable area, the use of defect management will reduce the risk of errors in storing the data. Moreover, advantageously, the formatting step can further comprise a verification step comprising checking for unreliable areas on the optical disc. Verify that the area that is not available will be identified before the disc is used. The present invention also encompasses a device for recording a rewritable optical disk according to claim 6. The present invention also encompasses a computer software product that, when executed on a general purpose processor, causes a recording device to perform the methods of claims 1 through 5. These and other embodiments of the invention will be apparent from the following detailed description of the preferred embodiments illustrated herein.

One of the parallel tracks is configured in a single spiral pattern. A disc may contain one or more layers of recordable information layers. Examples of known rewritable discs are CD-RW or DVD RW, dvd ram or bd re. For the case of cattle, further information about the physical structure and the information used for the site of the factory CD can be found in the reference materials and the mark of the optical debt test recorded along the track ( For example, a crystalline or amorphous mark in a phase change material is presented on the information layer. The track on the disc is indicated by a pre-bumped track structure provided during manufacture of the disc. For example, the track structure consists of a pre-engraving (10) enabling pre-groove-reading/writing human heads to travel along the track during scanning. The record of the track's track name u, track, " construction contains a change in the physical parameters, known in the art as a description, A* hangs as the period of the groove starting from an average centerline 120484.doc 200813999 Form of sexual radial displacement. The periodic wobble is further modulated so that further information is stored, such as a physical address indicating the location of the information unit. The beta can include a specific synchronization flag for determining the starting position of such information blocks. The location information is compiled into a group containing a predetermined number (four) of varying swings. However, the information encoded in the wobble is not limited to the address information. For example, in an example of a CD_RW disc, the following information is stored in the wobble: time information (physical address); write power at different rates; start time of introduction, extraction; and speed range. For • dVD+rw discs, the stored information can include: physical address, disc type (eg DVD+R, DVD+RW), disc size and maximum transfer rate, disc structure (eg: Recording layer, rewritable layer), recording density, data segment configuration (start and end addresses of the (four) segment), disc application code, disc identification, manufacturer identification, or write strategy parameters (speed range , for read/write power at several rates). In the example of a bd_re disc, there is a pre-recorded area known as a PIC area in which the following information can be stored: media type, write strategy and alternative strategy for different rates, speed range, for different rates Read power, disc size, number of layers, data section configuration (start and end addresses of the data section) This information is repeated five times for robustness. The above information stored in the swing is how to deal with the information of the disc. And it does not provide information on the actual recording on the disc. The disc 11 intends to carry user information according to a standardized format so that it can be played on a standardized playback device. The recording format includes information recording the encoding, and The logic is mapped to the recording space provided by the magnetic circuit 12, 120484.doc 200813999 and which will be described with reference to Figure lb. The recordable space is often subdivided into a lead-in area (10), which records the data section of the user data ( DZ), and lead-out area (LO). The lead-in area (LI) often contains the area in which the basic disc management information is stored, and provides information on how to actually access it. The disc description area of the section information. For example, the basic disc management information corresponds to the directory content in the cd system or the formatted disc control block in the DVD system. Further, at the logical level, The user data in the data section is arranged according to a file system containing file management information, for example, ISO 9660 for use in a CD system, which can be used as ECMA_U9, or UDF used in a DVD system, which can be used as ECMA_167. Such file management information is mapped to a predefined location 15 on the disc 11, often in the lead-in area (LI) or directly following the lead-in area (LI). The user recorded in the data section (DZ) The information may be further arranged according to an application format, for example, 'the application format includes a predefined file and directory structure. Fig. 2 is a schematic view showing a recording device for writing information on the optical disk 11 shown in Fig. 1a. The recording device is provided with a recording member for scanning a magnetic track on the optical disk, and the recording member includes a driving unit 16 for rotating the optical disk 11, a magnetic head 18, and a coarse positioning magnetic device. The positioning unit 21 of the magnetic head 18 in the radial direction is positioned, and a control unit 17. The magnetic head 18 includes a known type of optical system for generating a radiation beam 2〇 guided through the optical element, the optical element A light-emitting point 19 for focusing the radiation beam 20 onto the track 12 of the optical disk 11. The radiation beam 20 is generated by a radiation source (for example, a laser diode). The magnetic 120484.doc -10- 200813999 header further includes (not shown) a focus driver for moving the focus of the radiation beam 20 along the optical axis of the beam, and a tracking driver for finely locating the radiation point 19 in the radial direction of the center of the track. The tracking driver can include A coil for radially moving an optical element, or alternatively arranged to change the angle of a reflective element. In order to renew the information, the radiation reflected by the information layer is detected in the head 丨8 by a common type detector (for example, four quadrants) to generate a read signal and further detector signals, for example, The tracking error and focus error signal of the tracking and focus driver are controlled. To record information, the radiation beam 20 is controlled to produce an optically detectable mark in the recording layer. For this purpose, the recording device comprises a write processing means for processing the input message to generate a write number to drive the head 18, wherein the write processing means comprises an input unit 23; and the data processing means comprises a formatter 24 and a modulator 25. The control unit 17 controls the information recorded on the disc u or retrieved from the disc u and can be used to receive commands from the user or from the host computer. For this purpose, control unit 17 may include control circuitry, for example, a microprocessor, a program memory, and a control gate for performing the procedures described below with respect to FIG. Control unit 17 can also be implemented by a state machine in the logic circuit. The control unit 17 is connected to the input unit 23, the formatter 24, and the modulator 25 via a control line 22 (e.g., a system bus), and is also coupled to the drive unit 16 and the positioning unit 21. The input unit 23 receives and pre-processes user information. For example, when processing audio-video (video) information, the input unit 23 can include a 120484.doc -11 - 200813999 reduced input signal (such as analog audio and/or video, or digital uncompressed audio/video). ) Pressure I® components. Suitable compression components for audio are described in WQ 98/16014-Α1 (ΡΗΝ 16452), and appropriate compression components for video are described in the standard (180-1 £ (:13818). The input signal can be passed in advance. The output of the input unit 23 is passed to the formatter 24 to add control data and format the material according to the recording format, for example, by adding an error correction code (ECC) and/or interleaving. For computer applications, the information unit can Directly interfaced to the formatter 24. The formatted data from the output of the formatter 24 is passed to a modulation unit 25, which includes, for example, a channel encoder for generating a modulated signal that drives the magnetic head 18. Further, the modulation unit 25 includes a synchronization component for including a synchronization pattern in the modulation signal. The formatted unit presented to the input of the modulation unit 25 includes address information, and under the control of the control unit 17, It is written to the corresponding addressable location on the disc. The control unit 17 is arranged to record and retrieve the location data indicating the location of the recorded information volume. Formed on the disc. The mark can be any optically readable (tetra) shape L when recorded in a material such as a dye, alloy or phase change material, having a form of area that is different from the reflection coefficient of its surroundings, or when recorded In the form of a region obtained in a magneto-optical material having a magnetization direction different from its surroundings. Information for writing and reading formatting, error correction and channel coding rules for recording and usable on a disc is in this technique. It is well known, for example: from the cd system (IEC 908). In order to read the 'read signal processed by the read processing unit, the read processing 120484.doc 12- 200813999 single, including the demodulation transformer 26, the solution The formatter 27 and the output unit 28 for outputting information. The operations of the demodulation transformer 26, the formatter 27, and the output unit 28 are controlled by the controller 17. Therefore, the capture member for reading information includes the drive The unit 16, the magnetic head 18, the positioning unit 21, and the reading processing unit. Fig. 3 illustrates a method for disposing a disc according to the present invention in a flowchart. When the field disc is inserted into a device, the disc recognition step is first performed. 40 (DSC-REC). The steps are in this technique, and may include a first sub-step of determining the reflected radiation (eg, focus) parameters to determine whether the disc is a CD, a DVD, or BD type. After the disc type has been recognized, further basic disc information is captured to determine the basic read/write parameters and the location of the lead-in area, data section, and lead-out area. Note the basic disc information. It can be retrieved from the information encoded in the swing or by the information recorded in the lead-in area. In step 41, it checks whether the disc recognition is successful. If the disc recognition fails, there is no basic information about the disc. If available, the disc will be considered damaged in step 42 and rejected. If the disc recognition is successful, it is followed by the installation step 43 (〇1; 1^1), wherein in a first sub-step, the disc management information recorded in the lead-in area is retrieved. This poor news usually contains information that allows access to the logical layer. For example, in a CD RW system 'this is equivalent to reading the contents of the directory, in the DVD-RW system towel, which is equivalent to reading the formatted disc control block (FDCB) and in the BD-RE system, which is equivalent Read (temporary) defect management area ((T)DMA). The information present in it will indicate the format of the user's poor material on the disc (eg: Coffee or: (10)) and the file information form 120484.doc • 13- 200813999. In the next substep, the file information form is accessed and the disc installation is complete. μ In step 44, it checks if the disc installation was successful. If the disc is successfully installed, the end user can use the disc in step 45, for example, by reading and/or recording data. Disc installation can not be completely successful due to the following types of errors: - An error is encountered while reading the basic disc management information, so that no information about the user data on the disc is obtained during the installation step = Information about the class _ type, or information about where the file configuration information is recorded on the disc; " encountered an error in the purchase of the configuration information at 5th. When an error is encountered, the disc is considered damaged and rejected in the known disc player. However, in the method and apparatus according to the present invention, if the disc recognition is successful but the disc installation fails, rather than being rejected as a damaged disc, the rewritable disc is allowed to be in a formatting step 46 ( FORMAT) re-booking #式. This is based on the understanding that only a basic disc identification information that can be retrieved from the wobble is necessary to format a disc. It should be noted that when the latter type of error is encountered, a recovery step = (RECOV) can be performed prior to formatting, as will be detailed below. : The process of formatting a disc is known, and several options are often available. The process known as normal formatting in this art is a conventional way of simplification for entities such as CD or DVD discs. After the formal formatting process, the disc is fully formatted at the physical level. The formatting process includes a record lead-in area (LI), a write data section (DZ), a write-out area (l〇), and a verification data section as needed 120484.doc -14-200813999, and if a defect is to be used Management, initialize defect management. It should be noted that defect management can be handled outside the device, for example by a computer operating system. A second type of formatting process is known in the art as background formatting, which is a formatting process performed in the background during use of the disc in a recorder. After the background formatting process has been completed, the disc is completely physically formatted at the physical level. User data can be recorded on the disc during the background formatting process. The background formatting process may comprise the following steps: - initialization of defect management; de-icing material section 'which is not necessary, depending on the type of the disc; - finalization of the lead-in and lead-out sections; - early exit of the disc completion ( If applicable); - Restart background formatting on discs that exit early; - Verify (optionally selected by the host computer). As a result, the monthly landscape is seen as a more time-sensitive solution for users because only a minimum amount of data will be recorded on the disc during the initialization phase of the background formatting process, after which the disc Can be used by the application / user. The disc on which the background formatting process is valid can be formatted by the device in the background during the time when the application does not access the disc. In view of the fact that the disc is most likely to have an unavailable area due to previous attempts to install the disc, in a preferred embodiment of the invention, normal formatting is used instead of background formatting. This allows the full verification step 48 (VERIF) to be performed on the disc. Verify that it is a read and check 120484.doc -15· 200813999 The process of all the blocks in the data section of the disc. If an information block is found to be unreliable, it should be used to avoid the use of such information blocks to record user information.

The disc format, and a small number of disc formats used for the most A user resizing and minimum defect replacement areas. In the present invention, preferably and in practice, the heavily used disc format is used, in view of the fact that the disc is most likely to have an unavailable area because the attempt to install the disc fails. If the disc management information, i.e., the type and location of the broadcast management system, is read in one embodiment of the method, a recovery step 47 (RECOV) can be performed prior to the step of the simplification. f When an error occurs during the reading of the auditing system and the information, this can happen that the file system can only be partially installed. This can be achieved by installing a disc as a CD-ROM. In such instances, information located in a properly installed file can be recovered. In addition, if the optical disk drive can determine the logical disk layout of the disk, but when the replacement area used by the defect management system is full, in the method according to the present invention, in the recovery step 47, the disk will be installed as the only one. Read the disc. After installation, the user can choose to reorder the disc format or decide to perform a verification step that includes a bad area. This is based on the understanding that certain damaged areas are due to dust and grease appearing on the disc area and that the disc may have been cleaned, meaning that certain areas that have been marked as defective become available. If successful, the new replacement area becomes 120484.doc •16·200813999 is available so that the disc can be reinstalled as a rewritable disc. Regarding the implementation of the present invention in a device, it is noted that disc recognition, disc mounting, formatting, reading, and recording of information on a rewritable optical disc are known per se. In a preferred embodiment, control unit 17 is enabled to dispose of the rewritable optical disc in accordance with the new method described above, for example, by a suitable firmware. In an alternate embodiment, the connection to the capture and recording member via control line 22 and further connection to or inclusion in the control occurs.
